Problems solved by technology

However, when the relay indoor unit transmits the data of this unit and other indoor units at the same time, it is very easy to cause network transmission congestion, and even cause transmission failure, so the stability is poor

Abstract

The invention relates to the technical field of communication control of a multi-connected air-conditioning system, and specifically provides a relay device and a multi-connected control system, aiming at solving how to realize reliable communication between an outdoor unit and a batch of indoor units under the condition that the length of a communication bus is limited technical issues. For this purpose, the multi-connected control system in the present invention expands the communication distance through cascaded paths formed by a plurality of relay devices. Specifically, the cascade path transmits the control signals sent by the master control device / specific slave control device (that is, the slave control device directly communicatively connected with the master control device or a certain relay device) to the corresponding slave control device step by step, and The corresponding slave control device transmits the response signal fed back by the control signal to the master control device / specific slave control device step by step. Wherein, the relay device can communicate with the source node device (ie the master control device) and the destination node device (slave control device) respectively based on the master-slave communication mode.

Description

technical field [0001] The invention relates to the technical field of communication control of a multi-connected air-conditioning system, in particular to a relay device and a multi-connected control system. Background technique [0002] In the multi-connected air conditioning system, each outdoor unit can communicate with multiple indoor units, for example, each outdoor unit communicates with 64 indoor units. Specifically, the outdoor unit uses a master-slave communication method to communicate with the indoor unit. The outdoor unit serves as the master and sends query commands to some or all of the indoor units. The machines cannot communicate with each other. Based on the master-slave communication method, although one outdoor unit can control multiple indoor units, the number of indoor units is often limited by the length of the communication bus (the longer the communication bus, the greater the attenuation of the transmitted signal, so the length of the communication...
